Matters Need Attention
* Storage period of vacuum packaging module:
- Storage period: 12 months, storage environment conditions: temperature: <40℃, relative humidity: <90%R.H.
- After the module packaging is removed, the SMT assembly time limit:
- Check the humidity card: the displayed value should be less than 30% (blue), such as: 30% to 40%(pink) or greater than 40%(red) indicates that the module has absorbed moisture.
- Factory ambient temperature and humidity control: ≦30%℃, ≦60% R.H.
- After unpacking, the storage life of the workshop is 168 hours.
- If it is not used within 168 hours after unpacking, it needs to be baked, and the baking conditions are as follows:
- The module must be re-baked to remove the module moisture absorption problem.
- Baking temperature: 125℃, 8 hours.
- After baking, put appropriate amount of desiccant and seal the package.
- The number of vacuum packaging modules shall be subject to the actual number of packaging required by customers.
Note: The above packing method is subject to the customer’s requirements, and the packing is subject to actual shipment.

Label and compliance information
This device complies with part 15 of the FCC rules. Operation is subject to the following two conditions:
- this device may not cause harmful interference, and
- this device must accept any interference received, including interference that may cause undesired operation.
Warning: Changes or modifications to this unit not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment.
NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates uses and can radiate radio frequency energy and, if not installed andused in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
- Consult the dealer or an experienced radio/TV technician for help.
If the FCC identification number is not visible when the module is installed inside another device, then the outside of the device into which the module is installed must also display a label referring to the enclosed module. This exterior label can use wording such as the following: “Contains Transmitter Module FCC ID: 2BGY7-HZ01 Or Contains FCC ID: 2BGY7-HZ01”
Information on test modes and additional testing requirements
The modular transmitter is only FCC authorized for the specific rule parts (FCC Part 15.247) list on the grant, and that the host product manufacturer is responsible for compliance to any other FCC rules that apply to the host not covered by the modular transmitter grant of certification. The final host product still requires Part 15 Subpart B compliance testing with the modular transmitter installed when contains digital circuity.
Additional testing, Part 15 Subpart B disclaimer
When testing host product, the host manufacturer should follow FCC KDB Publication 996369 D04 Module Integration Guide for testing the host products. The host manufacturer may operate their product during the measurements.
